TJA1044T High-speed CAN transceiver with Standby mode

The TJA1044 is a high-speed CAN transceiver that provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

The TJA1044 offers a feature set optimized for 12 V automotive applications, with significant improvements over NXP's first- and second-generation CAN transceivers, such as the TJA1040, and excellent ElectroMagnetic Compatibility (EMC) performance.

Additionally, the TJA1044 features:

Ideal passive behavior to the CAN bus when the supply voltage is off
A very low-current Standby mode with bus wake-up capability

These features make the TJA1044 an excellent choice for all types of HS-CAN networks, in nodes that require a low-power mode with wake-up capability via the CAN bus.

Dual Sourced Manufacturing Base

The TJA1044T is supplied by two factories and customers ordering material will receive stock a combination of both sources. For quality purposes, production material is fully traceable.

Customers must ensure in their production qualification that both sources are qualified for use in their application. To facilitate this, NXP makes available two ordering codes for qualification samples, which guarantee stock from the individual sources. It is not possible to order production material via these ordering codes. The diagram below illustrates this ordering
